Wireless Temperature Contest Winner

Stephen Jacobs of St. Francis Xavier Secondary School is the winner of our contest for a classroom set (qty 10) of PASCO’s award winning wireless temperature sensors.

Please join us in congratulating Stephen!

Stephen’s submission was to use the PASCO Wireless Temperature Sensors to demonstrate the of Enthalpy of Hydration. We are looking forward to posting the results of his experiment in a future blog.

“After introducing the concept of enthalpy of hydration to my students, I give my students a small sample of cement (~ 10g), they add distilled water from a dropper (counting drops) or a buret (monitoring volume) and determine the ratio of water to cement sufficient create a mix that when placed onto a trowel, will remain as the trowel is rotated 90 degrees.

From this students learn the ideal ratio of water to cement.

Next, students are given a small quantity of cement (sufficient to fill a 400 mL beaker), and by ratio, the ideal amount of water is added slowly and the reactants are mixed with wooden paint sticks.  The thermometer is either coated with “Vaseline”/stopcock grease or “Saranwrap” and is placed into the center of the mixture in the beaker.  The temperature is monitored over time.  The cement cures with 24 hrs at which point the thermometer is removed.

Extensions…

  1. My students have coated the inside of used paper towel rolls with “Vaseline” and have made large quantities of cement to stuff inside these prepared rolls.  My students team up with Physics students to design different concrete compositions (fine sand, coarse sand, gravel (sorted by mesh size), and “rebar” (consisting of iron wire (available at TSC stores).  After chem students have measured the enthalpies of hydration, the physics students design experiments looking at the physics of cantilever beams…and test the beams to the point of failure.
  1. Instead of cement, I would combine calcium hydroxide and sand and have students measure the same reaction inside an improvised calorimeter.
  1. The topic extends far beyond the normal curriculum as my students learn about restoration work of historic structures and the fact that cement was invented just before the time of the Romans.”

  • Wireless Spectrometer Big Hit With Students – PASCO’s wireless spectrometer has been utilized very well by our earth science and physical science teachers. It’s an excellent piece of equipment and we have very much enjoyed its addition to enriching our classroom. It definitely brings students to a higher level of understanding wave interaction at a molecular level.

  • Excellent Smart Cart – I thought the cart was excellent. The quick sampling rate for force will be very useful for momentum and collision labs we do. I’m recommending we include this in our order for next school year.

  • Your lab equipment is of the highest quality and technical support is always there to help. During the 25 years we have used a wide array of lab equipment including computer interfacing. Your Pasco line has a high profile in our lab and will continue to do so far into the future.

  • Datalogging Activities are Cross-Curricular

    Throughout the province of Nova Scotia, PASCO’s probeware technology has been merged with the rollout of the new P-6 curriculum. We chose a number of sensors for use with our project-based activities. Both the functionality and mobility of PASCO’s dataloggers enable students to collect authentic, real-world data, test their hypotheses and build knowledge.

  • We have a large number of PASCO wireless spectrometers and love how they have improved the learning experience for our students.

  • During distance learning due to COVID-19 school shut down, I was given a short window to collect what I could from my classroom to teach online. The PASCO wireless sensors and Smart Carts were my top priority to collect to implement distance learning. By sharing experimental data with students via SPARKVue, the sensors were pivotal in creating an online experience that still allowed students to grow with their lab skills. It was easy to record videos of the data collection and share the data with my students. They did a phenomenal job examining and interpreting the data.
